audio not working after Mojave update on 2015 MB Air

I updated to Mojave and the internal speaker are not seen, nor is the internal microphone seen. I can hear audio with bluetooth headphones and on Airplay on the TV. I have uninstalled and reinstalled the OS. I have plugged headphones in and it does not see them either. I have done a PRAM and all other resets without any change. I have a late 2015 MacBook Air. Does anyone have a fix for this? I can hear the "chime" every time I reload the OS, but once it is loaded...nothing in the settings showing internal speakers or microphone.

MacBook Air (13-inch, Early 2015), macOS Mojave (10.14), sound

I solved it by doing a clean re-install of Mojave.

Hi MoonJ,

I tried both of those and there are no hardware problems and when I logged onto another user account, there is still no sound. I have also erased my hard drive and reinstalled a clean copy of Mojave, and it is exactly the same thing. I hear chimes when the computer restarts, but no sound or option for sever or microphone when I go to settings.

Any other suggestions?

I have the same problem as well - after a Mojave update, I can no longer receive audio input from my Behringer UMC204HD interface. I can receive audio playback through it, but the audio input is not working. This is the case both for Steinberg CuBASE Pro, as well as in Garage Band. I have followed all of the steps listed below on this page as potential fixes, but I am left with no input signal going through to my recording software. To check this was not a problem with the interface, I reconnected it to another Mac running High sierra, and the audio in and out works perfectly - so this narrows it down to being a Mojave update issue. Mac Support, please please help to try to solve this problem - it is just a complete disaster for me at the moment, where sound recording is one of the main reasons for me supporting multiple Mac computers. Many thanks

Same problem with 404HD .... Audio out but none in to GB. Found the stupid privacy setting and checked GarageBand but still no audio in from the Behringer. Only from the built in mic. Way to go Apple. Last update it was no plugins now no audio???

Hi, after updating to OS 10.14.4 the audio disappeared to VideoGlide / Plexgear / Moviesaver 500.

I've deleted:
com.apple.audio.SystemSettings.plist
com.apple.audio.DeviceSettings.plist
and made PRAM reset.

The problem remains!

Update: Change the above discussed privacy setting and reboot. Hope this saves another musician 2 hours of valuable time.

When I select "microphone" while in Privacy there's nothing to select. It just says "apps that have requested access to your microphone will appear here". But there's nothing there. Any ideas?
